More accurate layout detection in CRL::GdsDriver. 

* Bug: In CRL::GdsDriver::hasLayout(), a Cell was saved in the GDSII
    stream only if it has a layout, but the check was not accurate
    enough. In the Arlet6502, the whole core was missing.
      Now check for the abscence of Plugs (not unfinished Nets) and
    PLACED/FIXED instances.
